Abstract

L'invention concerne un cylindre de frein (1), destiné en particulier à des véhicules ferroviaires, comprenant un dispositif de verrouillage (10) pour le verrouillage mécanique de la force de freinage, et un piston de frein de service (2) qui peut se mouvoir axialement dans un boîtier (1) sous l'effet de l'action d'un agent sous pression et qui est couplé à un barillet (5), le barillet (5) étant pourvu d'un filetage non autobloquant (9) qui est en prise avec un écrou fileté (7) monté rotatif dans le boîtier (1), le dispositif de verrouillage (10) coopérant avec la denture (8) de l'écrou fileté (7). Le cylindre de frein est caractérisé en ce que le dispositif de verrouillage (10) comprend un ou plusieurs cliquets d'arrêt (11, 12), un piston de commande (13), un poussoir de desserrage d'urgence (14) et un élément de verrouillage (17) du poussoir de desserrage d'urgence (14).
